Her interest in herbal therapeutics and healing modalities began in 1992 with a focus on Aromatherapy and later developed into a fascination with herbalism and nutrition. Over the years she has studied the art, science, and safety of essential oils, medicine-making, and herbalism with various teachers. In 2011, she became certified as a Clinical Aromatherapist through the Institute of Integrative Aromatherapy (with Laraine Pounds, RN, MSN, CMT). In 2015, moved by the plethora of questionable information on the internet and the increasingly unsafe use of essential oils by the public, Kat developed Esenta, The Aromaticum App as a means to provide safe and reliable information on the therapeutic uses and dilutions of EO. Kat then continued her studies in the healing arts at CSCH, where she earned her certifications in Clinical Herbalism and Nutrition. She currently lectures on various topics in the CSCH Fundamentals and Advanced programs, writes articles on aromatherapy, and offers workshops to students and the public on topics including medicine-making, EO safety and toxicology, and comparing herbalism with aromatherapy. In addition to her focus on education, Kat offers all-natural body care products, custom natural perfumes, and holistic health support through her business, Roots of Alchemy / Esenta, LLC.er to create a curriculum that addresses the complexities, depth, and beauty of the human relationship to self, to others, and to the natural world.
